help with fret board set up issue
Hello TBer's, need some help/advice. A recent pawn shop find has scored me an '81 G&L L1000. The neck is in incredible condition. I took it home and performed a routine set up on it. Neck responds well to truss rod adjustments. set relief at .015" and action at 4/32" at 17th fret. nut height is just barely below .022".
here's the issue; when I get to playing from 16th/17th frets and up it's fretting out on the remaining frets. Is this an issue of these frets not being as worn as the others? Or is it a neck pocket shim issue? finger board issue?
If I raise action up higher it merely moves the fretting out issue up a few frets.
what do you think?
Not that your bass is experiencing what mine was, I have a L2000 fretless from the late '80s and it had a similar issue. I set the neck as flat as possible but there was an obvious hump where frets 15,16, etc would be. I had a pro re-level it by planing out the hump. Good as new.
Someone who makes more sense will chime in eventually. Out of curiosity, does yours have the 3 bolt with micro-tilt?
it's a 3 bolt. I don't even know what the micro tilt is? can you enlighten me?
If there is a small hole in the plate, inside you'll find a small screw. Its there instead of having to shim the neck and helps during setups to align the neck angle. I've never had to adjust mine because I was able to find the hump in the fingerboard with a straightedge and knew the micro tilt wouldn't help. I DO know that if adjustment is needed, loosen the neck screws a little first.
If I were you, I'd adjust the TR to get the neck as flat as possible and use a straightedge to determine if the board has a hump and go from there. If it does, the only fix may be defret and re-level then re-fret. A skilled luthier may be able to dress/level the frets enough to make the humorless noticeable.
EDIT: I just Googled "G&L micro tilt" and the first result was G&L owners manual in PDF form. It has great instructions (I think on page 9).
Read the instructions carefully, especially regarding how much to loosen the three screws before you start twisting the allen key in the hole on the neck plate. It's a great invention, and it was very well executed by both Music Man and G&L (and quite unlike how Fender executed the design) but if you don't do it correctly you'll cause more problems. MUCH better than the trial-and-error process shimming requires.
thanks for the info. guys. It does have the little hole on the neck plate. I will surely look into it (the manual that is).
You may want to review this- similar...
Learning how to adjust the micro tilt is all fine, but that's not going to solve the problem that you have with this neck. From your description, it has what I call the 12th fret kink, also often described as the "ski jump" problem. Over time, the neck has bent slightly in the 10th-14th fret area, effectively causing a ramp at the heel. It's a common problem on older bolt-on necks.
The frets need to be re-leveled, or in the worst case, the frets need to be pulled and the fingerboard resurfaced. Playing around with the truss rod or the micro-tilt isn't going to solve it.
Darn auto correct.:D
I'd try to adjust the micro-tilt first, then maybe the relief if it helps: it's free.
Then neck work only if that doesn't help enough...
gonna have some time tomorrow to mess with it. I'd like to learn how to utilize the micro tilt as I have another '81 L1000 as well. thanks for all your inputs, keep em coming.
My gut feeling is what Bruce Johnson posted. I'm thinking that if it's a neck tilt issue it would affect more than just the last 6 frets. I used it at rehearsal Fri. night and it played really nice (below 16th fret).
read this first:
read, thanks. I will give it a try.
Don't bother trying it. The micro tilt is better than a business card, and your problem is more likely to be a hump, or ski jump.
Before you mess with the micro tilt, adjust the relief out to make the neck as flat as possible and straightedge the board. You'll see the hump more clearly then. Read Bruce J's post.
will do that too.
Ok, did a lot of messing around and here's the result(s).
no real noticeable "ski Jump" going on. Performed adjustments with the micro tilt and it's considerably better. raised action slightly and fretting is gone. What is noticeable is it will require a little bit of fret filing at 18/19 and the action will be able to get back down where I like it.
thanks for help everyone
If it requires fret filing at the 18/19th, then that probably is the 12th fret kink or "ski jump" condition that I described. Unless the frets are actually raised up from the fingerboard.
When you put a straightedge on the fingerboard, if the maximum relief is around the 12th-14th fret, then that's the 12th fret kink condition. A neck without the kink will have the deepest relief around the 5th fret, and will be nearly flat from the 10th to the 20th. That's what you really want to see for the lowest action.
